NAME

       HTML::RewriteAttributes - concise attribute rewriting

SYNOPSIS

           $html = HTML::RewriteAttributes->rewrite($html, sub {
               my ($tag, $attr, $value) = @_;

               # delete any attribute that mentions..
               return if $value =~ /COBOL/i;

               $value =~ s/\brocks\b/rules/g;
               return $value;
           });

           # writing some HTML email I see..
           $html = HTML::RewriteAttributes::Resources->rewrite($html, sub {
               my $uri = shift;
               my $content = render_template($uri);
               my $cid = generate_cid_from($content);
               $mime->attach($cid => content);
               return "cid:$cid";
           });

           # up for some HTML::ResolveLink?
           $html = HTML::RewriteAttributes::Links->rewrite($html, "http://search.cpan.org");

           # or perhaps HTML::LinkExtor?
           HTML::RewriteAttributes::Links->rewrite($html, sub {
               my ($tag, $attr, $value) = @_;
               push @links, $value;
               $value;
           });

DESCRIPTION

       "HTML::RewriteAttributes" is designed for simple yet powerful HTML attribute rewriting.

       You simply specify a callback to run for each attribute and we do the rest for you.

       This module is designed to be subclassable to make handling special cases eaiser. See the
       source for methods you can override.

METHODS

   "new"
       You don't need to call "new" explicitly - it's done in "rewrite". It takes no arguments.

   "rewrite" HTML, callback -> HTML
       This is the main interface of the module. You pass in some HTML and a callback, the
       callback is invoked potentially many times, and you get back some similar HTML.

       The callback receives as arguments the tag name, the attribute name, and the attribute
       value (though subclasses may override this -- HTML::RewriteAttributes::Resources does).
       Return "undef" to remove the attribute, or any other value to set the value of the
       attribute.

THANKS

       Some code was inspired by, and tests borrowed from, Miyagawa's HTML::ResolveLink.
